Alfa Channel® Polymer Concrete Trench Drain

Alfa Channel® is a modular, pre-cast, pre-engineered polymer concrete (PC) trench drain system that has an interior channel width of 4″. The system includes 30 sloped channel sections of 1m (3.27′) each with a built-in slope of 0.6%. The system also includes 4 additional neutral or non-sloping channels that may be inserted for additional trench length. A variety of gratings and covers provide load capabilities from pedestrian up to large aircraft and severe point loads. The system is complemented by both In-Line catch basin and 12″ x 19″ modular catch basin assemblies. The modular design of the Alfa Channel system provides true on-site adaptability and cuts down overall project costs by reducing excess materials.

NFPA CODES AND TRENCH DRAIN- Request a UL listed product

Various NFPA codes require drainage components to be made of non combustible materials. The intent of these codes are to prevent the spread of flame. Since trench are collection points of flammable liquids and heavier than air vapors, trench drains can spread fire and contribute to smoke development even when empty. All of MultiDrain Polyester Polymer Concrete products carry the UL 723 Classified mark for Class A fire rating for flame spread and smoke development.

Selecting a trench drain with the proper material properties is critical to the life cycle of the product and life safety of a buildings inhabitants. Demand a UL Classified product.
